WILLIAM B. BOOKER AND GOVERNOR D. WARREN, OF VICTOR, COLORADO; SAID WARREN ASSIGNOR TO SAID BOOKER.

BOILER-CLEANER.

SPECIFICATION forming part of Letters Patent N o. 628,388, dated July 4, 1899. Application filed October 22, 1898. Serial No. 694,339. (No model.)

To a. whom it may concern: 1

Be it known that. we, WILLIAM B. BOOKER and GOVERNOR D. WARREN, citizens of the United States,residing at Victor,in the county of El Paso and State of Colorado, have invented new and useful Improvements in Boiler-Cleaners, ofwhich the following is a oif and when moved in the opposite direction to float or swing away from the bottom of the boiler, all of which. will be fully described hereinafter and particularly referred to in the claims.

The object of our invention is to provide a simple, cheap, and efiective boiler-cleaner of the construction hereinafter shown and described, whereby the operator may sweep the bottom of the boiler by means of a handle from outside thereof.

In the accompanying drawings, Figure 1 is a central longitudinal vertical section of a horizontal boiler, showing our invention applied thereto. Fig. 2 is a vertical sectional view taken on the line 2 2 of Fig. 1. Fig. 3 is a view similar to Fig. 1, showing a larger number of brushes connected to the supporting-bar.

Referring now to the drawings, Aindicates an ordinary horizontal tubular boiler, and B the usual tubes or fiues thereof.

Our invention pertains to a bar 0, situated within the'boiler and provided at proper intervals throughout its length with upwardlyprojecting oppositely extending hooks a, adapted to curve over and catch upon the upper sides of the two central tubes or flues, as clearly illustrated in Fig. 2.

A rod D passes through a suitable stuffingbox F at one end of the boiler, and the inner end of this rod is suitably connected with the adjacent end of the supporting-bar C.

G is a T-shaped handle adapted to be attached to the projecting end of the rod D and boiler.

attached with the supporting-bar 0 through the medium of the pivotal bolts cl and which permit the brushes to swing, as shown in dotted lines, Fig. 1. The ears, however, are provided with rearwardly-projecting shoulders or stops 1), adapted to engage the supportingbar 0, and thus prevent the brushes from swinging out ofa vertical line when the supporting-bar O is moved in the direction indicated by arrow in Fig. 1. When moved in the opposite direction, however, the brushes will swing away from and out of engagement with the bottom of the boiler, as will be readily understood.

H is the blow-off, situated at the bottom of and at one end of the boiler, preferably at that end opposite to the operating-handle G.

In operation the handle G is moved back and forth, thereby reciprocating the supporting-bar C. When the rod is pushed in, the brushes assume a vertical position and sweep the scale and dirt from the bottom toward the blow-off. lVhen moved in the opposite direction, the brushes swing away from the bottom, as before stated, and swing over the scale and dirt brushed by the preceding brush. The brushes should be placed at intervals along the supporting-bar O a few inches less than the stroke of the piston-that is to say, should the stroke of the piston be thirty-six inches the brushes should be placed along the supporting-bar about every thirty inches, so that in sweeping the bottom of the boiler a stroke should be given for each brush before the scale started by the first brush atthe front or head of the boiler will be deposited by the last brush at the back head or blow-off of the In this way the bottom of the boiler is entirely swept from end to end by a short movement or stroke of the piston. r

The device is so constructed that the interior of the boiler is not disturbed in attaching it, it requiring only, an opening for the stuffing-box through which the reciprocating rod passes, and the invention is thereby adapted to be attached to horizontal boilers of most all forms now in common use.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-

1. In an improved boiler-cleaner the combination of a boiler having longitudinally-extending parallel tubes, a non-rotatable brushsupporting bar situated below said tubes and having rigidly-connected upwardly and oppositely extending hook-shaped arms engaging the said tubes and supporting and holding the longitudinal brush-supporting bar against rotation, depending brush-supporting brackets having upwardly-extending ears pivoted to said supporting-bar,a web spanning the space between the cars at a point below and to one side of the pivotal point of the ears to lock the brackets against the swinging movement when the bar is moved in one direction but permitting a swinging movement when moved in the opposite direction, the said webs engaging directly the under side of the supporting-bar, and an operating handle passing through one end of the boiler and connected with the said supporting-bar, substantially as described.

2. In an improved boiler-cleaner the combination with a boiler havinglongitudinallyextending parallel tubes an elongated nonrotatable brush-supporting bar situated under the tubes and provided with rigid upwardly and oppositely extending supportingears at each end thereof, brush-supporting brackets comprising a curved base carrying a brushing-surface, and an intermediately upwardly extending rigid arm having at its upper end upwardly-extending rigid parallel ears situated at opposite sides of the said supporting-bar and pivoted thereto, a web extending transversely of the said ears at a point below the bar and traveling in the path of the supporting-bar to engage directly its under side for holding the brushbrackets against movement in one direction but permitting it free movement in the opposite direction, and a handle passing through one end of the boiler and connected with the said supporting-bar, substantially as described.

, In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.
